SPECIFICATION forming part of Letters Patent No. 585,168, dated June422, 1897.

Application filed December l, 1896. Serial No. 614,068. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK A. ZEIGER, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inMiter-BoXes, of which the following is a full, clear, and exactdescription, reference being had to the aecompanying drawings, whichform a part of this specification.

My invention relates to certain new and useful improvements in theconstruction of ruiter-boxes; and my invention consists in features ofnovelty hereinafter described and claimed.

Figure Irepresents a perspective of my improved miter-box, showing sawheld in its suspended position. Fig. II is a transverse section taken online II II, Fig. I. Fig. III is a transverse section taken on line IIIIII, Fig'. II. Fig. IV is a detail view showing bearingball and holdersecured to theback of the miter-box. Fig. V represents a front elevationof the miter-box. Fig. VI is a top view. Fig. VII is a rear elevation.Fig. VIII is a bottom view. Fig-IX is a detail view showing manner ofpivoting the guides to the miter-box, said figure being a section takenon line IX IX, Fig. X. Fig. X is a transverse seetiontaken on line X X,Fig. IX. Fig. XI is a section taken on line XI XI, Fig. XVI. Fig. XIIrepresents a side elevation. Fig. XIII is a transverse section taken online XIII XIII, Fig. XVII. Fig. XIV is a section taken on line XIV XIV,Fig. VIII, showing means of securing the adjustable guide f-rame orstandards. Fig. XV is a detail front elevation of one of the leatherguides. Fig. XVI is a detail front elevation, showing spring forsupporting a saw. Fig. XVII is a detail front elevation of one of thestandards, showing leather bearing or guide in position.

Referring to the drawings, l represents the miter-box, having ahorizontal supportingbottom 2 and a vertical back 3, the back 3 havingthe usual recess 4, through which the saw extends when the device isbeing used.

5 represents a front and 6 a rear standard or guide, preferably made inthe form of a channel-iron, having flanges 7 8, leaving the verticalchannel 9 extending the length of the standards. The standards arepreferably made in one piece and are connected at their lower ends by asection 10, which extends beneath the lnitersbox from one standard tothe other. The guide-standards are pivoted to the'rear of the bottomboard 2, as shown at 1l. (See Fig. IX.) The board 2 is provided with arecess l2, into which fits a rounded plate 13 on the rear standard, thusforming a bearing on the upper side of the bottom board 2, the

standard being provided with a plate or extension 10, extending beneaththe bottom board 2 and havinga screw 15 inserted therein and engagingthe bottom board, which permits the standard to swing as upon a pivot.Thus by taking hold of the front standard and moving it sidewise anyangle desired may be obtained between the standard and the ruiter-box,the usual angles being shown at 16 on the board 2, but, of course, thestandard can be so adjusted as to divide up the angle shown.

17 represents a bearing-bar, preferably curved in form and secured tothe bottom of the ruiter-box near its forward edge and extending beneaththe section lO, which connects the front and rear standards.

18 represents a curved bar secured to the bottom of the miter-box, butextending above the section l0. The curved bar 18 is provided with aseries of orifices I9.

2U represents an aperture extending through the section 10, saidaperturebeing on line with the center of the curved bar 18.

21 represents a spring-plate having its inner end secured to the sectionIO at 22 and having a pin 23 secured near its outer end, said pinextending upward and of the proper size to pass through the orifice 2Oin the section l0 and into the apertures 19 in the curved bar 18. Bypressing down upon the outer end of the spring 21 the pin 23 iswithdrawn from the apertures 19 in the curved bar 18, leaving thesection 10 free to be moved either to the right or the left to the angledesired. Then by releasing the pressure on the spring 2l the pin 23 willenter one of the apertures 19 and thus secure the section 10 andstandards at the proper angle at which they have been set. Theguide-standards 5 6 are provided with vertical openings 24, so as to ad-IOO mit the passage of.' the saw. In order to form a guide that will notinjure the teeth of the saw and at the same time have lasting qualities,I provide guides 25, preferably formed of sole-leather, said guidesbeing inserted into the vertical hollow spaces 9 of the guidestandards 56. The guides 25 are provided with vertical slots 2G, extending nearlythe length of the guides, but have a short scction 27 at their tops,intowhich the slot 2G does not extend, the slot-s 2G, of course, being forthe passage of the saw 2S. (See Fig. I.) The guide-leathers are easilyplaced in position in the standards and are provided with grooves 29,running parallel with the central groove 2G.

30 represents inwardly-extending lips on the flanges 7 of theguide-standards, said lips entering the said grooves 29 in the leatherguide and holdiugit in its proper position in the guide-standards.Should the grooves 29 become worn to too great an extent, so that a trueguide would not be provided for the saw, the leather guides can bereadily reversed, grooves being formed in the rear side of the same forthat purpose, if desired. The front standard 5 is cut away at thebottom, as shown at 3l, in order to give free access to the spring 2lwhen itis desired to change the angle of the guides.

In order that the forward end of the saw shall not descend. too low andthus damage the miter-box, I provide a cup 32, adjustably secured to therear standard by means of a set-screw 33. In this cup I place a ball 34,formed of leather or some other suitable material, a portion of the ballextendinga short distance above the top of the cup, the center of theball being on line with the groove 26 in the guide-leather, the resultbeing that when the saw has descended a sufiieient distance to sever themolding, or whatever the carpenter may be sawing, the teeth of the sawwill come in contact with the ball 34.- and roll with the saw as it isforced back and forth, the rolling motion preventing the saw fromcutting the ball and the ball preventing the saw from passing below apredetermined point.

In the use of a miter-box when it is desired to adjust the angles of theguides or to rest the saw for other reasons and for the protection ofthe teeth it is desirable that the saw be suspended in the frame orguides, and to arrive at this end I have placed springs near the top ofthe front guide-standard, said springs being preferably made in twoparts, having their lower ends secured at 3G to the sides of thestandards and having their top ends secured at 37 to a cross-bar 38,which braces and connects the top of the standards. The springs thusform an inverted-V shape, into which the upper edge of the saw is wedgedas it is forced upward and held therein until removed by a slightdownward pressure.

I claim as my inventionl. A miter-box comprising a box proper, verticalstandards having a pivoted bearing connection with the box properconsisting of a circular plate providing an upper bearing, a sectionconnecting the standards and providing a lower bearing, and a screwextending through the connecting-section; subst-antially as set forth.

2. A miter-box comprising a box proper, having a divided back, and aball loosely supported at the lower end of the divided portion, andadapted to receive the -impact of the saw and to rotate freely in anydirection thereunder; substantially as set forth.

3. A miter-box comprising a box proper, guide-standards, and aloosely-supported ball adapted to receive the impact of the saw and torotate freely in any direction thereunder; substantially as set forth.

4. A miter-box comprising a box proper, guide-standards, a cup securedto one of the standards, and a ball loosely/*supportedin the cup andadapted to receive the impact of the saw, and to rotate freely in anydirection in the cup; substantially as set forth.

5. A miter-bex comprising a box proper, guide-standards, an adjustablecup secured to one of the standards, and a ball loosely supported in thecup and adapted to receive the impact of the saw and to rotate freely inany direction in the cup; substantially as set forth.
